MANUFACTURE OF HOOKS.

SPECIFICATION forming part of Letters Patent No. 371,502. dated October11, 1887.

Application filed July 18, 1887. Serial No. 214,593.

To all whom it may concern.-

Be it known I, HENRY HOFFMAN, J r., of South Norwalk, in the county ofFairfield and State of Connecticut, have invented a new Improvement inthe Manufacture of Wardrobe- Hooks; and I do hereby declare thefollowing, when taken in connection with accompanying drawings and theletters of reference marked thereon, to be a full, clear, and exactdescription of the same, and which said drawings eonstitute part of thisspecification, and represent, in-

Figure 1, a perspective view of the hook complete; Fig. 2, a side viewof the blank from which the hook is formed; Fig. 3, a side view of theblank, showing the lower arm as bent into its final shape; Fig. 4, arear view of the blank, showing the base portion split; Fig. 5, a rearview showing the two wings of the base portion turned, respectively, tothe right and left to form the base.

This invention relates to an improvementin the manufacture of that classof wardrobehooks which consist of a base adapted to be secured to thewall, with two arms extending therefrom, upon which garments or otherarticles may be readily hung, the construction being specially adaptedto the better class of hooks, or such as made from the finer metals,

as brass or bronze.

These hooks usually are constructed with two arms, as seen in Fig. 1,each curved upward. The finer metal requires to be finished andpolished. The cost of so doing adds mate- 5 rially to the expense of thehooks. Again, the lower arm being necessarily curved upward and towardthe arm above it, makes a space between its end and the arm above itnarrower than the space between the arms nearer the Consequently thisinterior space cannot be finished on the wheel, but requires hand-workor peculiar mechanism for finishing it. The whole surface of the hookand base being irregular makes the expense of finishing 5 the casting sogreat that the demand for this better class of hooks is necessarilylimited.

The object of my invention is to cheapen the construction of this classof hooks, and so that they may be produced at a cost but slightly (Nomodel.)

greater than that of the cheap or common castiron hooks.

I first produce the blank, as seen in Fig. 2, and this is best done bycutting it from sheet metal of a thickness suitable for the transversestrength of the hook. The upper arm is cut in its final curved shape andextends from a center or base, B. The lower arm, 0, in the blank,instead of being curved upward toward the other arm, diverges from it,so as to make the space between the arms wider at the end 6c of the armsthan nearer the base. The blank thus cut is easily finished, the shapeof the arms permitting the polishing-wheel to work between them, so asto reach the entire surface between the two arms. The base portion, B,as formed in the blank, is in the same plane with the arms A C. Thisbase portion is divided vertically, as seen in Fig. 4, the divisionbeing in the plane of the hooks. After the base portion, B, has beenthus split, forming two wings, DE, the two wings are turned,respectively, to the right and left, as seen in Fig.

5, and so as to bring their rear surface into the same plane. The wingsthus turned outward form the base, and they are pierced, as shown, forthe insertion of screws, so that by the base the hook may be secured tothe wall in the usual manner. The lower arm, C, after havingbeenfinished upon the inner surface, as before described,'is curvedupward, as seen in Fig. 3, so that the two arms present substantiallythe usual shape for a two-armed hook, and the hook when complete doesnot differ essentially in its general appearance from that of'casthooks; but because I am enabled to cut the blanks from sheet metal andto finish the surface while in a flat condition, and subsequently tobend the arm C into the required shape, I very greatly cheapen the costof production of this finer grade of hooks, and not 0 only is theconstruction cheapened, but a much finer finish may be given to the hookthan it is practically possible to give in the usual cast hooks.

It will be understood that if but a single arm 5 is required either armmay be omitted, accord ing to circumstances, or more arms may be added,if in the same plane, when desired, as

in other constructions of hook, (not necessary 2. That improvement inthe manufacture of to be illustrated,) the base always being firstwardrobe-hooks having two arms which conformed in the plane of thehooks, then divided sists in preparing the blank with the upper andturned to the right and left. arm curved to its ultimate position,finishing r 5 5 I claim or polishing the blank, and then curving the 1.That improvement in the manufactureof lower arm to its final position,all substantially ward-robe hooks having one or more arms l as setforth. w

which consists in preparing the blank in proper outline, splitting therear portion vertically, 5 HENRY HOFFMAN 10 then turning such splitportions outwardly to Witnesses:
